I've had both styles and can't decide which were more of a PITA to clean!
108s were so much easier, but they have their issues with corrosion around the bolts and lacquer lifting, so I replaced them with a set of 5 spoke Style 295s from an E89. A happy bonus was that with different offsets they sat much further out in the arches without needing spacers.
But wheel choice is very much a personal preference.
